Industrial BiofoulingDetection, Prevention and Control
edited by James Walker Susanne Surman

Biofouling and biofilms are the terms used to describe the attachment of biological material
to surfaces. A number of organisms including bacteria, protozoa, amoebae, fungi,
barnacles and other organisms have been shown to form biofilms that create nuisances
in man-made environments.

Biofilms occur and are a problem in the water service utilities,
many industrial processes including the food, pharmaceutical, paint, oil processing and
manufacturing, and engineering industries. In addition they may create havoc in medicine
and dentistry. Industrial Biofouling covers biofouling/biofilms in domestic,
industrial and health related fields in which they are a persistent problem.
